Appiication filed August 12,1922; Serial No. 581,436..

To all whom it may concern V 7 Be it. known that I, ELIJAH BRooKns, subject of the King of Great Britain and Ireland, and resident of Old House Green, l Scholar Green,Stoke On-Trent, in the county of Staiford, Eng1a-nd, earthenware manufacturer, have invented a certain new and useful Machine for Use in the Manufacture of Teacups, Breakfast Cups, Beakers,aand it Other Vessels or Articles offPottery (for which I have filed application in Great Britain by application for Patent No. $2,707, dated the. 29th day of: Jnly,;-l 92-l), of which the following is a specification.

My invention relates to a new or improved machine for use in the manufacture ofteacups,- breakfast cups, beakers, and other vessels or articles of pottery, the object being to provide a machine toexpeditiously and efiiciently finish the clay articles after they have been shaped or cast. 7

My invention will befully described with reference to the accompanying drawings, in which- Fig. 1 is a part front elevation of the machine const-ructed'according to my said in vention, certain of the. details. not being. shown,

Fig. 2 is a side. elevation thereof,

Fig. 3 is a sectional plan through line Fig. 4: is a sectional plan through linev B-B of Fig; 2, illustrating the means for arresting the rotatable chuckv which carries the clay article,

Fig. 5 is a part sectional plan, or a portion of that illustrated at Fig- 4 showing the parts in a different position to be hereinafter referred to,

Fig. 6 is a front elevation of the upper. part of the machine drawn to an enlarged scale, the parts being inthe position they assume when the clay article W in the-chuck is being operated upon, 1

Fig.7 is a side elevation of Fig.6, Fig.8 isan elevation'o-f the'rotatable chuck andwcutting, device for severing the upper edge of the clay article." The clay article is removed 'from'therotatablechuck so so as to clearly show the operation'of the cams;

Vari'oushollow vessels or clay articles can be cut off, grooved, edgedand. rounded by my improved machine but I will describe. the machine for edging and rounding cup bodies, W. The cup body lV is cast from clay; slip in a plaster mould in, the ordinary way but instead of casting ,itthe correct height of a. cup it is cast a little higher and being rounded by the tool; and the, finished 7 Figs. 14r to16 are: enlarged views of the clay" article W raised out of contact with.

the chuck so as to be'readily removed.

chuck is securedlat the end of a. sleeve. f the lower end working in an adjustable foots'tep bearing f carried onthe machine frame. Extending through the said sleeve f isa. slidable rod- 9 carrying a disc 9' atits upper end, the latter being arrangedto move Vere tically inside the chuck e. -The clay cup body W is placed on the discg? (Fig. l0),

the disc is, then automatically moved downwards to allow the outside. of the clay cup W to make contact with the interior of the chuck as shown at Fig. 11 in which position the chuck and clay cup revolve together, the knife or cutter Y (Fig. 11) then severing the splayed topof the clay body. 1m.- 7

niediately thisseverance has taken place a rounding tool- Z is brought into'use to round the top edge W (Fig. 12). The chuck I e is prevented fromrotating w-hilstthe disc g and the finished article NV thereon is raised in a position to be readily taken off as shown at. Fig. 13. 7

The sleeve f rope. Pulley it connected f thereto the upper -,flange k ofs ai'd pulley being .of such a width toenable'a brake y'- te make ,contactjltherewith- When necessary.

.Tlhe bi e-kc .j is hinged? at j? to. the table by as shown at Fig, 1,, the oppositeend to the hinge being connected by a short arm [alto an adji stable bolt Z hinged at'm to a slide 0, the said bolt Z (Fig. 4:) being provided with a cushion spring m and freely moving in a hole 75 in the short arm 70. When the slide is moved forward in thedirection of the arrow X (see plan Fig. at) the brake'y' is thrown out of contact with the pulley 7t and the travelling driving rope p is taken into contact with the pulley h by the small grooved pulley g on the slide 0 as shown at Fig. 5to rotate the chuck e and clay cup 7 therein. The reverse orbackward travel of the slide 0 takes the brake 7' into contact with the pulley h and allows the travelling driving rope p to clear the grooved periphery h of the pulley 71. as shown at Figs. 2 and 4. The said slide 0 receives its motion. from a two-armed lever r secured to a rocking shaft 8 and having its upper end pivotally connected at t to a link a which is also pivotally connected at o to the slide 0. The lower short arm of'the lever 'r is provided with a bowl 2 which is always in contact at its lower end and connected at 8 to the slide, the weight tending to keep the bowl 2 on the lower end of the arm 1 always in contact with the face of the earn 1. If desired a spring 9 connected to the slide 0 and to the front of the frame a may be employed to draw the slide 0 forward. The said spring 9 is broken off to clearly show the other mechanism. During the continued rotation of the shaft 0 the cam 1 secured thereon forces the slide inwards as shown at Fig. 2 the weight 7 drawing it forward when that portion of the cam face l nearest the driving shaft 0 reaches the bowl 2, the continually moving rope p then rotating the chuck e whilst the top edge of the clay cup is being severed and also rounded in a manner to be herein described.

Figs. 1 and 2 illustrate the machine in its initial position that is, the weighted arm 10 raised ready for the chuck e to receive a clay cup body W, whilst Figs. Gand 7 show the weighted arm 10 in its horizontal position when cutting off and rounding the upper edge of the clay cup W.

All the cams illustrated on the drawingsare in the position they assume when the hinged weighted arm 10 is raised. As before stated cam 1 fixed on the shaft'c is for operating the slide 0 through the two-armed lever'r. Cam 20 secured'to the shaft 0 is for the purpose of operating the lever E the part 20 of the cam 20 lifting the lever to'its full extent, this action causing the rocking shaft .9 to sufiiciently rotate and lower the lever G, fixed to the shaft 8. The said lever Gr being connected at 11 through .ished clay body W' therein.

W israised out of.

the cable 11 and at 11 "to the hinged weighted arm 10 pullsthe latter down in ing the bell-crank lever back again to nor- I ma l position shown in full lines 9) immediately the projection 14 leaves it. A stop 29 on the bell-crank lever 15 limits its outward stroke.

When the weighted arm lO- descends and 7 the knife Y has cut off the top of the lay body the rounding tool Z'comes in operation finishing off the cut edge as shown at Figs. 6 7 and 12.

The chuck 6 with the clay body WV coinmences to revolve as the-knife "Y approaches the clay, the revolution of the chuck a being accomplished immediately the bowl 2 on lever 1" takes against the face of cam 1 (Fig. 14-.) which allows the lever 7 to move the slide outward the grooved pulley g thereon then taking the travelling rope 32 against the grooved pulley it which being fastened on the sleeve 7 rotates the chuck e ust after the brake 7' has been disengaged as shown at Fig. 5. The said chuck c rotates sutliciently so that the top W of theclay cup body is cut off and the top edge W is rounded by the tool Z. To'facilitate the settingor adjustment of the rounding tool Z it is carried 7 r in a slide in a V shaped groove in' plate 82, the latter being adjustably connected to The bell-crank lever 15 being ful A horizontal the weighted arm 10. A spring 33 is 'connee-ted at 34 to the plate 32 and to thelow'er end of the slide carrying the tool Z. To lower the rounding tool Z a set screw 35 is rotated, the end 36 thereof pressing the slide down. hen the setscrew 35 is slackened the spring raises theslide.

Cam QOallowsthe lever E to move downwards to the positions'hown at Fig. 2, the

weighted hinged arm 10 being then free to move to its initial position at Fig. 1. When the lever E is moving downwards as stated the lever 1 moves the slide 0 inwardsby which means the grooved pulley g clears the travelling rope p (Fig. 1), the brake 7' makes contact with pulley h andinstantly prevents rotation of the chuck c with the cut and-fin- The finished clay body the chuck e to the position Fig. 13, immediately the chuck ceases to rotate. I This is accomplished by the vertical'square rod 9, pro vided with the disc g at its upper end, the

lower end of the square rod 9 ported by a slide 18 guided'by afixed. bracket 19. The

7 said slide 18 is connected by a link 21 (Fig.

3) to a lever 22 loosely mounted on the shaft s, the said loose lever having a short arm 22 carrying a bowl 23 which makes contactwith cam 30 fixed on the shaft c. When the bowl 23'is against face 24: of the: cam 30 the disc 9 in the chuck cremains atitshighest position but as the bowl 23 moves along face 25 of the cam 30 the disc in the chuck moves down being at its lowest position when bowl 23 is nearest boss 26 of the cam 30. As shown at Figs. 11 and 12 the disc 9 is clear of the clay body w when the latter isin contact with the chuck e.

The machine is operated as follows When the weig ted hinged arm is in the position illustrated at Fig. 2 the disc 9 is in its highest position, a cast'clay body W is placed on the disc as shown at Fig. 10 which is then stationar the driving lOUB bein 3 .L b

tion Fig. 13 enabling the finished articleto be readily-removed. Another clay body W is placed in position and vthe arm pulled down again to form a similar operation as before. r

Clay articles or vessels of various sizes may be cut oil and finished in precisely the same way. i

It has previously been proposed to construct a machine for cutting off and shaping the upper edges of clay vessels for making pottery, such machine comprising an intermittently rotating chuck having a disc raised and lowered therein and a mechanically-op erated hinged arm carrying a shaping tool. What I claim as my invention and desire to secure by Letters Patent is 2+ 7 1, In a pottery machine, a chuck for holding the article providedwith a vertical driving shaft, a lever pivoted to rock in a hori zontal plane and provided with a knife for 7 being sup plate l'r' securedto a vertical cutting ofi'the upper part'iof article when as revolving with the chuck, anarm pivoted to' work in a vertical plane and provided with a I 7 projection which operates V the said lever when the arm" s lowered, and a rounding toolfcarried; by the said arm and engaging: upper with the rim oflthe article aft'erits part'hasbcen cut oif'by theknife.
